J. D. ENGLISH NONSKID CHAIN Patented Jan. 20, 1925.

UNITED STATES PATENT CFFICE.

NONSKID CHAIN.

Original application iiled August 10, 1921, Serial No. 491,109. Divided and this application led September 30, 1922. Serial No. 591,650.

To all whom it may concern.'

Be it known that I, J oHN D. ENGLISH, a citizen of the United States, residing at Watertown, in the county of Codington and State of South Dakota, have invented certain new and usefullmprovements in Nonskid Chains; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention relates to non-skid chains, and is filed as a division of my copending application entitled Chain cou-4 pling, led August 10, 1921, under Serial Number 491,109-, and formally allowedApril 21. 1922.

To the above end, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

In the accompanyin drawings, which illustrate the invention, ike characters indicate like parts throughout the several views.

Referring to the drawings Fig. 1 is a fragmentary side elevation of a pneumatic tire mounted on a disc wheel and having applied thereto the improved non-skid chain;

Fig. 2 is a fragmentary plan view of the invention; and

Fi 3 is a detail view with some parts sectione on the line 3--3 of Fig. 2, on an enlarged scale.

The numeral 4 indicates a pneumatic tlre mounted on a disc wheel 5 and having applied thereto the improved non-skid cham which comprises two sectional side chains 6, cross tread chains 7, and oblique cross tread chains 8. Each section of each side chain 6 has, at each of its ends, a hook-like link 9, and each cross tread chain 7 has, at each of its ends, a hook-like link 10.

The sections of the side chains 6 and cross tread chains 7 are connected in rectangular arrangement by rings 11 at the corners of the rectangles, and with which rings the hook-like links 9 and 10 separably interlock. The oblique cross tread chains 8, in each rectangle are made u of sections connected by a rin 12, at their intersection, and havin at eac of their four outer ends hook-like lmks 13 which are separabl interlockac with the rings 11 between the ook-like liiks 9 and 10. In actual construction, the hook-like links 13 will have a twist like the main links in the chains so that they will lie flat against the sides of the tire 4.

As best shown in Fig. 2, the sections of the side chains 6 and the cross tread chains 7 are of the same length so that they may be interchangeably used, thus making it necessary to carry repair chain sections of one length only, and which sections may be used in replacing broken sections of the side chains or broken cross tread chains. To remove a broken side chain section or a broken cross tread chain, it is only necessary to pry open the respective hook-like links to separate the broken sections from the rings 11 and then apply a new section by interlocking its hooklike links, whichv are primarily open, to the rings 11 and pressing or pounding the same closed.

Suitable couplings, preferably of the type disclosed and claimed in my above identified application, will be used for separably connecting the ends of thf` side chains 6.

In addition to a com lete non-skid chain. one or more rectangu ar sections thereof may be carried for use. as an emergency chain, and applied to a tire when the wheel is stuck in mud, loose sand, or snow. Such an emergency chain may be secured to the spokes o the wheel or in any other suitable lhat I claim is:

1. A non-skid chain comprising side chains and cross tread chains forming a rectangle, rings at the corners of the rectangle, said side chains and cross tread chains having at their ends hook-forming links separably attached to the rings, and a pair of oblique cross tread chains in the rectangle, connected at their intersection and-having at their ends hook-forming links se arably attached to the rings between the ook-forming links of the side chains and cross tread chains.

2. A non-skid chain comprising side chains and cross tread chains forming a rectangle, said side and cross tread chains being separably connected at the corners of the rectangle, said side and cross tread chains being interchangeably usable.

I In testimony whereof I aiiix my signature.

JOHN` D. ENGLISH.
